Multifunctional environment-friendly screen residue testing device

The utility model discloses a multifunctional environment-friendly screen residue testing device which comprises a container, a screen is arranged at an opening in the top of the container, a frequency modulation vibrator for providing screening power is arranged below the container, a PH tester for detecting the PH value of a solution in the container is installed on one side of the container, and the PH tester is connected with the container. According to the device, the frequency modulation vibrator is used for providing screening power, the power of the frequency modulation vibrator is convenient to control, variables can be stably controlled, the influence of external factors in the screening residue test is smaller, then the test result is more accurate, and in the test process, the test efficiency is improved. The PH value of the solution can be measured by utilizing the PH tester, the particle sizes of different flame retardants or different products can be compared and judged by observing the sedimen
